Member Function Documentation

◆ compositingType()

CompositingType KWin::QPainterBackend::compositingType ( ) const

finaloverridevirtual

Implements KWin::RenderBackend.

Definition at line 27 of file qpainterbackend.cpp.

◆ createSurfaceTextureWayland()

std::unique_ptr< SurfaceTexture > KWin::QPainterBackend::createSurfaceTextureWayland ( SurfacePixmap * pixmap )

overridevirtual

Reimplemented from KWin::RenderBackend.

Definition at line 32 of file qpainterbackend.cpp.

◆ isFailed()

bool KWin::QPainterBackend::isFailed ( ) const

inline

Whether the creation of the Backend failed.

The SceneQPainter should test whether the Backend got constructed correctly. If this method returns true, the SceneQPainter should not try to start the rendering.

Returns: bool true if the creation of the Backend failed, false otherwise.

Definition at line 44 of file qpainterbackend.h.

◆ setFailed()

void KWin::QPainterBackend::setFailed ( const QString & reason )

protected

Sets the backend initialization to failed.

This method should be called by the concrete subclass in case the initialization failed. The given reason is logged as a warning.

Parameters

reason The reason why the initialization failed.
